OVERFLOW AND WASTE FOR BATHS OR BASINS.

SPECIFICATION forming part of Letters Patent No. 556,388, dated March 17, 1896. Application filed March 13,1895. Serial No. 541,550. (No model.)

To all whom it ntay concern.-

Be it known that I, JAMES J. ADE, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Overflows and \Vastes for Baths or Basins, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part thereof.

In the drawings, Figure 1 is a vertical section through a basin and the overflow and waste passages thereof containing my invention. Fig. 2 is a detail section containing the overflow and waste passages in vertical plane, showing a modified form of my invention. Fig. 3 is a plan view of a modified form of the fitting shown in Fig. 2. Fig. at is an enlarged detail section of the lower end of the pillar which receives the fitting in a plane at right angles to the plane of the section in Fig. 1. Fig. 5 is a side elevation of the handle or pull which operates the valve. Fig. 6 is a detail section of the fitting secured to the slab for the guidance and support of the pull or handle, section being taken at the plane 6 G on Fig. 1, looking upward.

The basin A has formed integrally with it in the earthenware a vertical passage A, which extends directly through from top to bottom of the earthenware pillar a, located at the rear or side at which the water connections are located. It is designed that the slab B above the basin shall have an aperture B continuing the vertical passage, so that before the metallic fittings are applied there is a direct vertical passage at the top of the slab opening at the bottom of the earthenware. Through the wall of the basin the overflowapertures a lead into this vertical passage A. From the bottom of the bowl the ordinary waste-passage A leads into the vertical passage A at the side. C is a metallic fitting designed to afford a seat for a valve D, which is adapted to close the communication from the direct waste-passage A into the vertical passage A. A suitable seat is not easily formed in the earthenware in this position, and one purpose of this invention is to retain the advantages of the general arrangement shown and at the same time get a perfect seat for the valve, which is operated by a pull-knob at the top of the slab, as will be hereinafter more particularly described.

The fitting 0 comprises the conical valveseat C having a lateral opening C which, when the fitting is in place, registers with the mouth of the waste-duct A The vertical passage A, which is cylindrical throughout, has a slight enlargement at the lower portion, forming the small shoulder A and in this enlarged portion I form two longitudinal grooves a a at opposite sides, which lead from the lower end of the earthenware a short distance upward and there meet and merge in interior circumferential grooves a a eX- tending ninety degrees, more or less, around the vertical wall of the vertical passage.

The fitting C has two lugs C 0 projecting at opposite sides at the lower end of the conical portion C and adapted to enter the grooves a and a and by this means the fitting is adapted to be inserted and locked in place by a short turn after the lugs c reach the portion o of the grooves. The lower end, C of the fitting C is cylindrical and eX- teriorly threaded and of the interior diameter of the smaller end of the conical portion C, and is long enough to protrude below the fitting a sufficient distance to receive the cap E, which is interiorly threaded and adapted to screw onto the exterior threaded portion, C of the fitting C, the flange of the cap embracing the circular boss which is formed by the lower end of the pillar a, through which the vertical passage A is formed. This fitting C is designed to be inserted from the bottom up against the shoulder A, which is reached by the upper edge of the conical portion C when the lugs C are properly set in the grooves a The space that is left between the conical fitting and the cylindrical wall of the c avity into which it is thus entered the plumber will fill with putty, and the cap E being screwed on the joint is complete without the use of any washers or lead.

D is the valve, which is exteriorly conical and adapted to fit the conical seat C and is hollow, so that when it is seated, closing the aperture C an unobstructed passage-way is open through it from the overflow into the final waste -discharge. A connectingrod, preferably of two or more parts loosely jointed together, connects the valve to the eye f in the crossbar f of the cylindrical guide extension F of the pull-knobF. To guide and seat this knob, a thimble G is provided, adapted to pass through the opening in the slab and stopped by a suitable flange-shoulder G at the top of the slab, the lower end of the thimble being threaded, so that it may receive a clamp-n ut G2 below the slab, whereby the slab may be bound tightlybetweenthe flange-shoulder G and said socket. The upper end of the pillar a has a recess or rabbet a, formed around the upper end of the passage A, which accommodates the nut G so that it is not necessary to recess the slab for this purpose. The thimble Ghas an interior bead or inwardly-projecting band G around the upper margin of its aperture, said head or band having-the notches g g at opposite sides, and the cylindrical guide-flange F of the knob has a lug or tooth F adapted to enter one of the notches, and at the upper portion it has two lugs F F at opposite sides and ninety degrees from the tooth F adapted simultaneously to enter the two notches. The lower ends of the lugs F are above the upper level of the tooth F a distance a little greater than the width of the bead or band G. This structure adapts the knob to be inserted through the thimble, the tooth F passing down through either one of the notches until the lower ends of the lugs F rest upon the top of the thimble. In this position the valve is off its seat, but entered into the fitting, so that it will be guided to its seat, if allowed to drop. The rotation of the knob ninety degress admitting the lugs F to the notches, respectively, permits the knob to drop until stopped by the interior projecting flange G which is formed around the lower margin of the fitting G of the thinlble, and in this position the valve is fitted in the fitting C and the waste is closed, while the overflow-passage is still open freely through the hollow valve.

Fig. 2 shows a modification of this device, in which the valve instead of being hollow is solid, the overflow-passage being formed alongside of it behind the valve-seat. In this case the valve-seat is formed in a frustum of a cone which may be described within the cone frustum which constitutes the body of the fitting C, as is shown in the principal form, such described cone frustum merging at one side in the wall of the circumscribed frustum. (L represents this described valve-seat. The

seat proper, of course, is only the portion surrounding the aperture or mouth of the wastepassage A but in order to cause the valve to come to this seat and be held against it the cone frustum is completed in skeleton, comprising the upper segmental web, (1 the lower segmental web, 0 and a single oblique bar 0 connecting them in position preferably directly opposite the wasteopening. The jointed connection from the valve to the pull device at the top of the pillar permits the valve, although not centrally located within the passage A, to seat accurately by gravity, and to be easily pulled off its seat by the jointed connection, although the pull is not exerted directly in line with the axis of the valve. When the valve is seated it will be understood that overflow passing out at the top of the bowl will escape behind the valve cage or seat described.

I have shown a special form of strainer II at the waste-outlet of the basin. This strainer has a short vertical annular flange 11, at the lower edge of which, at two opposite points, are provided horizontally-projecting lugs 11 I1 The earthenware has two notches h h at opposite sides of the circular opening formed to receive the strainer, and at the lower edge of the aperture I form rabbets 11" 11 extending ninety degrees from the notches 7L respectively, so that when the strainer is introduced in place by passing the lugs II II down through the notches h h until the upper flange of the strainer seats in the rabbets h formed for that purpose around the upper margin of the opening, the lugs H 11" are in position to pass into the segmental rabbets 7?. h as the strainer is rotated ninety degrees or less, and thereby the strainer is held into place without cement, belts or screws.

I claim--- In combination with the bath tub or basin having the pillar A apertured from top to bottom and communicating laterally with the waste-outlet and overflow-outlet, the metallic seat-fitting adapted to be inserted in the lower end of the pillar and provided with a lateral aperture to register with the waste-outlet, said fitting being largest at the upper end, whereby a cavity is left around it accessible at the lower end of the pillar after it is inserted adapted to receive putty or cement, and a cap nut screwed onto the protruding end of said fitting to close the lower end of said cavity and bind the fitting to the pillar and receive final waste connections: substantially as set forth.

In testimony whereof I hereunto set my hand, in the presence of two witnesses, at Chicago, Illinois, this 7th day of March, 1.895.
